OWNER’S MANUAL
Contractor Fence Assembly
Model CNS-SFA

1. You must install a rip fence before using your contractor saw. Attempting to use the saw without the rip fence
could result in serious personal injury.
2. Always use a rip fence when making rip cuts. Never perform a ripping operation freehand or a serious injury
may result.
3. Always use a push stick or push block when your hand comes within 6 inches of the blade. Attempting to use
the rip fence for narrow cuts without a push stick or push block could result in a serious personal injury.
4. Do not use the miter gauge when making rip cuts.
5. While making bevel cuts, use the fence only on the right side of the saw blade to prevent the blade from
possibly contacting the fence. The brake will activate if the spinning saw blade comes into contact with the
aluminum in the rip fence.

• Mount the left rear rail (the shorter rail)
to the rear of the table and to the left extension
wing using three M8 x 16 hex screws , three
M8 lock washers , and one M8 hex nut . Insert one hex
screw into the hole in the extension wing and then use a lock
washer and hex nut to hold the screw in place, as shown. The
other two hex screws thread into corresponding holes
in the cast iron table. Place a lock washer on each
screw before threading them into the holes. Hand
tighten the hex screws; do not fully tighten them.

Installing the Fence Rails
Assembly
• Locate the front rail, the left and right rear rails, and hardware
pack #3. All of the hardware needed to install the rails is located
on hardware pack #3. In order to easily identify the hardware
used in each of the following steps, the different pieces of
hardware are numbered on the hardware pack and in the figures.
If you are missing hardware pack #3 or any of the other fence
assembly components, call the SawStop Service Department at
503-682-6222 for replacements.
Youwill also need the following tools
to complete the fence assembly:
1. two 13 mm wrenches
2. a level or straight-edge
3. a rubber hammer or mallet
• Adjust the position of each square head screw so that all eight
screws align with the corresponding mounting holes in the front
edge of the table top and extension wings. Position the front rail
against the edge of the table with the eight screws
extending through their corresponding mounting holes.
Make sure the rulers on the front rail are facing up.
• Place an M8 lock washer and thread an M8 hex nut on
the back of each of the eight square head screws, but do not fully
tighten the nuts at this time. Position the front rail so that the left
end of the rail extends about ⁄ inch past the edge of the left
extension wing.
1718
• Use a straight-edge to level the rear edge of the left extension
wing to the cast iron table top. Youmay have to pull up or push
down on the outer edge of the extension wing to level it. Once the
rear edge of the left extension wing is level, use 13 mm
wrenches to fully tighten the hardware that mounts the
left rear rail. Repeat this process to level the rear edge
of the right extension wing and secure the right rear rail.

to level the rear edge of the right extension wing and to secure the
right rear rail to the saw.
8. Locate the material support shelf, the two large storage hooks and the
two small storage hooks. Take the material support shelf and insert two
M8 x 20 square head screws from hardware pack #3 into the holes on one
end. Loosely place an M8 lock washer and a M8 hex

square head screws into the slot on the right end of the front rail until the holes in the rear of the material
support shelf line up with the holes in the
rear rail. Use two M8 x 16 hex screws, two
M8 lock washers, and two M8 hex nuts
to mount the material support shelf to the
rear rail (see Fig. 9). Use a straight-edge to
level the top of the material support shelf
with the cast iron table top. Use two 13 mm

16. Use a straight-edge to level the front edge of the left extension wing to the cast iron table top (see Fig. 16).
You may have to pull up or push down on the outer edge of the extension wing. You also may need to remove
the fence from the table to provide clearance for the straight-edge. Be careful not to change the position of the
front rail. Once the front edge of the left extension wing is level, use a 13 mm wrench to fully tighten the nuts in
the front rail that extend through the left extension wing and the table top. Repeat this process to level the front
edge of the right extension wing and the material support shelf and then fully tighten the remaining nuts in the
front rail.

15. With the fence unclamped and still against the right side of the saw blade, gently tap one end of the front rail
with a rubber hammer or mallet to move the rail to the right or left until the cursor on the right fence scale is
aligned with zero on the underlying ruler (see Fig. 15). Be careful to tap the front rail gently or the plastic cap
at the end of the rail may be damaged. Once the right fence scale reads zero the front rail is in the correct
position.

Using Your Rip Fence
8 SawStop Contractor Fence Assembly
To use the rip fence, begin by placing it on the
fence rails so that the clamp at the rear of the fence
engages the rear rail and so that the front of the
fence engages the front rail. You can use the fence
on either the left or right side of the blade for non-
bevel cuts. If you plan to make bevel cuts, use the
fence only on the right side to prevent the blade from
possibly contacting the fence. After placing the fence
on the rails, lift the red handle up to the unlocked
position (see Fig. 18) and slide the fence to the left
or right until the distance between the blade and the
fence is approximately equal to the desired width of
cut.
The precise width of cut is shown by the indicator
lens on the front of the fence (see Fig. 19). The
lens on the left indicates the width of cut when the
fence is on the left side of the blade. The lens on
the right indicates the width of cut when the fence
is on the right side of the blade. Each indicator lens
in positioned above a ruler on the front rail. Each
lens has a red cursor line that indicates the precise
width of cut. To read the width of cut, look down at
the cursor line. The mark on the ruler that is directly
below the cursor line is the width of cut.
Adjust the position of the fence until the cursor is
directly over the desired width of the cut. Once the
fence is in the correct position, push the red locking
handle down to the locked position. The fence is
now locked in place and ready for use.
The rip fence included with your contractor saw is
used to guide material parallel to the blade when
you make rip cuts (cuts that are length-wise along
the grain of the wood). The fence must always be
used when making rip cuts. The fence also allows
you to precisely set the width of your rip cuts. When
not in use, you can store the fence on the two fence
storage hooks mounted to the material support shelf
(see Fig. 17)

unlocked position

right indicatorleft indicator

The fence must be parallel to the cutting
surface of the blade to make an accurate rip
cut. Use the following procedure to check if
the fence is parallel to the blade.
Slide the fence until the left face of the
fence is adjacent to one of the miter slots
and clamp it in place (see Fig. 21). If the
left face is parallel to the miter slot, then no
further alignment is needed. If the left face
is not parallel to the miter slot, unclamp
the fence and then reclamp it to see if it
straightens out.
If the fence is still not parallel to the miter
slot, unclamp the fence and loosen the two
socket head screws in the top of the fence
with a 5 mm hex key (see Fig. 21). Then
align the side of the fence with the miter
slot, clamp the fence in place and re-tighten
the screws. The fence is now set parallel to
the cutting surface of the blade.
The fence should be securely locked to the rails when the red handle is in the downward locked position. If
the fence locks tightly and cannot be easily moved, no further adjustment is necessary. However, if the fence
does not lock tightly, or if the fence locks too tightly, you will need to adjust the clamping force applied by the
fence.
If adjustment is necessary, the
clamping force is set by the 10 mm
hex nut in the end of the fence (see
Fig. 20). To increase the clamping
force, turn the hex nut clockwise
with a 10 mm socket. To decrease
the clamping force, turn the hex
nut counter-clockwise. Lock the
fence in place with the red handle
and verify that the fence is locked
securely to the rails. If further
adjustment is necessary, repeat the
steps above.
